General function description
3.1. Display icon description
3.1.1. Bar graph for power
The bar graph for power is used to indicate the percentage of the actual measured value of the
total apparent power value of the power meter to the rated value. The rated value of total apparent
power is equal to the effective phase number * rated voltage value * rated current value.
Figure 3-1: Bar graph for power
Note:
1), Under the measurement type conditions of three-phase four-wire 3CT, three-phase three-wire
3CT and single-phase two-wire 3CT, the effective phase number is equal to 3. Under the
measurement type condition of three phase three-wire 2CT and two phase three-wire 2CT, the
effective phase number is equal to 2.
2), The rated voltage is equal to the rated voltage of the secondary side * the rate of the voltage
transformer.
3), The rated current is equal to the rated current of the secondary side * the rate of the current
transformer.
4), For Example: Under the measurement type conditions of three-phase four-wire 3CT, suppose
the rated voltage of the secondary side is 110V, the rated current of the secondary side is 5A, the
rate of the voltage transformer is 100, and the rate of the current transformer is 40, then the rated
voltage value is 110*100=11kV, and the rated current value is 5*40=200A, so the rated value of the
apparent power is 3*11000*200=6600kVA.
5), Rated voltage of the secondary side defaults to 230V and rated current of the secondary side
defaults to 5A. Both values can be set by communication commands. For specific register
information, please refer to the relevant communication protocol documents of the product.

3.1.2. Digital I/O indicating icon
The digital I/O indicator icon is used to indicate the status of the digital I/O interface of the current
power meter.
Figure 3-2: Digital I/O indicator icon
If the icon only shows the circle without the dot inside, it means the current state is OFF. If both
circle and dot show, it means the current state is ON. As shown in Figure 3-2, DI-1 and DI-2 are
ON states, DI-3 and DI-4 are OFF states, DO-1 is OFF states and DO-2 is ON states.
3.2. Multi-tariffs function
The multi-tariffs function refers to the function that the meter realizes time-sharing measurement of
electric quantity. The power meter divides the 24 hours of a day into several time periods, and then
specifies the rate number for each time period. Then the power meter accumulates the amount of
electricity in time division according to the pre-divided time period, and stores it to the position of
the rate number corresponding to each time period, so as to realize the function of time-division
measurement of electricity.
The power meter used the method of the tariff number correlation to the starting time point to
realize the tariff segment division. The power meter support up to 8 starting time points and up to 4
tariff segments (T1, T2, T3 and T4).
Figure 3-3: The starting time points of the tariff segment
As shown in Figure 3-3, 06:10 designated as the start time of tariff 1 (T1), 12:00 designated as the
start time of tariff 2 (T2), 18:00 designated as the start time of tariff 3 (T3), 21:00 designated as the
start time of tariff 4 (T4), so tariff 1 time range is 06:10 to 12:00, tariff 2 time range is 12:00 to 18:00,
tariff 3 time range is 18:00 to 21:00, tariff 4 time range is 21:00 to tomorrow 06:10.
Note: The tariff parameters can be set by pressing the button (Refer to step 5 in 4.5.7), also can be
set by communication commands (Please refer to the relevant communication protocol document
for the register address).
3.3. Demand calculation method
3.3.1. Fixed block interval
The block intervals are consecutive, the power meter calilates and updates the demand at the end
of each interval.

-
Figure 3-4: Diagram of fixed block interval calculation method
As shown in Figure 3-4, the first demand calculation is made at the 30th minute, and the demand
calculation data is between the 15th and the 30th minute. At the 45th minute, do the second
demand calculation, and the demand calculation data is between the 30th and the 45th minute.
3.3.2. Sliding block interval
The block intervals are sliding, the power meter calculates and update the demand at the sliding
speed.
Figure 3-5: Diagram of sliding block interval calculation method
As shown in Figure 3-5, the first demand calculation is made at the 15th minute, and the demand
calculation data is between the 0th and the 15th minute. At the 16th minute, do the second
demand calculation, and the demand calculation data is between the 1th and the 16th minute. At
the 17th minute, do the third demand calculation, and the demand calculation data is between the
2th and the 17th minute.
3.4. System current direction correction function
This function is to set the wiring direction of the CT of the current channel through internal

KMF000 series

-
processing of the power meter, without rewiring the CT in this process. In the process of wiring, if
the current transformer is installed in the opposite direction or connected to the power meter in the
opposite direction, the user can use this setting function to ensure that the current measured by
the power meter is in the correct direction without rewiring the current transformer.
Note: This function can be set by pressing the button (Refer to step 3 in 4.5.4), also can be set by
communication commands (Please refer to the relevant communication protocol document for the
register address).
3.5. Description of energy display format
The energy display format of power meter is to automatically adjust the display effective digit
according to the energy value. The change process of effective digit of energy display is shown as
follows:
0.00 kWh/kvarh -> 999999.99 kWh/kvarh -> 1000000.0 kWh/kvarh -> 9999999.9 kWh/kvarh ->
10000000 kWh/kvarh -> 99999999 kWh/kvarh -> 100000.00 MWh/Mvarh -> 999999.99
MWh/Mvarh -> 1000000.0 MWh/Mvarh -> 9999999.9 MWh/Mvarh -> 10000000 MWh/Mvarh ->

is shown below. Please refer to Appendix C for the specific display screen diagram.
1. Three-phase four-wire (3P4W)
Note (1): This is only shown if the power meter is a multi tariff model, such as PAC5010 and PAC5110.
2. Three-phase three-wire 2CT (3P3W 2CT)

3. Three-phase three-wire 3CT (3P3W 3CT)
Note (1): This is only shown if the power meter is a multi tariff model, such as PAC5010 and PAC5110.
4. Single-phase two-wire (1P2W)
Note: In single-phase two-line mode, the measurement voltage input end is connected to the
same voltage line, and the current input end can be connected to three current transformers to
measure three different single-phase loads. Therefore, the product can be used as a product with
a 3-channel measurement loop.
Note (1): This is only shown if the power meter is a multi tariff model, such as PAC5010 and PAC5110.
